Re: [Emc-users] CAD/CAM for LinuxCNC

I can also report some success with Fusion 360. I have produced some GCODE for milling quite easily, creating the CAD model directly in Fusion 360. I have also done some turning work, starting with the Siemens turning Post and modifying it for LCNC. So far I have found it easy to modify. The G33

Re: [Emc-users] Yaskawa or not

The Servopack number is SGDB-03VDY1 like I mentioned below The motors are AC servos - USAGED-30V22 and USAGED-05V22K The machine is a CNC glass cutter that has a horde of pneumatic and hydraulic functions. The model is an Intermac Fox 3700 I would attempot to just replace the pc and control

Re: [Emc-users] Yaskawa or not

Yaskawa has been making motors and drives for a long time, and have made a lot of different kinds, using all manor of controls. Your going to have to give us more information for us to give you a recommendation. But on the surface I would have to suggest, if there isn't anything wrong with

Re: [Emc-users] Yaskawa

Thinking a bit more, I see no reason that any drag knife software couldn't be used. If you use rectangular based cuts only, and you handle dong breaks manually, it should be easily doable. Cutting rounded or serpentine cuts are had due to the breaking methods that need to be used. Machines that

[Emc-users] Very cheap stepper drives

I purchased some very cheap stepper drives based on the TB6660 Toshiba chip a little while ago for a very much "budget driven" controller build using LinuxCNC for a Sherline Mill and Lathe. They are all over Ebay and the part number of the side is HY-DIV268N-5A I think I paid $17 each for

Re: [Emc-users] Yaskawa

Years ago I worked for DeMichele Systems in College Station, TX. They are now DeMichele Systems in Mesa AZ. Their specialty was optimized cutting for the Flat Glass industry. Back 'in the day' it was Fortran programs that ran on Cromemco Z80 systems, but that is ancient history. Their software

You guys don't miss much. I grabbed a few of those today.. They had 4 of the larger Nema 23 combos in stock when I found them. Someone is dumping some stock. Here is the manufacturer of the MB450A drive. http://sumtorelec.com/product.asp?plt=38=3=0=0=0 It make a lot more sense if you run

Greetings; I have a motor that at one time drove a small paper shredder, but the knives wore out wal too soon so I salaged the motor & gear train & binned the rest. Its a series wound motor, and I have it broken out to 4 wires now, so its reversible with a dpdt relay driving either the field

It looks like a pulse and dir setup from what I see on page 544. There is mention of speed and torque reference but it does not make sense. -- Original Message -- From: "andy pugh" To: "Marius Liebenberg" ; "Enhanced Machine Controller (EMC)"

Re: [Emc-users] Yaskawa

Nothing special that I saw. It is a rotary knife type machine with a driven C axis for the knife rotation. I will attempt to use the old CAM software. It does generate some G code that I might have to convert somehow. The trick come in the pressure and cutting speed and the angle of the

Hi All I have been asked to upgrade a machine that has a very old control system still running on DOS. It is fitted with Yaskawa SGDB-03VDY1 drives. I cannot seem to find reference to that extract number. There are two 2.9Kw motors and one 0.45Kw. They all have incremental encoders. From the

Have you tried contacting Intermac to see if they could get you some schematics? I think your going to want them. Unfortunately I think I've heard they aren't the easiest company to work with so you might be out of luck, but it doesn't hurt to try. And from the pictures google brings up of

Ted The machine is 15 years old. DOS for sure. The screens look like the old pascal interface for cga screens. The new machines still have the same model number but it is not the same. The local agent does not have access to the manual as the supplier refuses to give it. They want the customer
